At the JWST town hall at #AAS240, Scott Friedman of STScI says 6 of 17 JWST observing modes have now been declared science ready (2 of them earlier today.) By end of next week should have 13 of 17 modes commissioned.
Concluding comment from his presentation on JWST commissioning: JWST is working better than expected by almost every measure. #AAS240
With commissioning of the James Webb Space Telescope nearly complete, project officials and NASA leadership promise the telescope’s first images will stun scientists and the public alike.During a media event at the Space Telescope Science Institute (STScI) here June 29, project managers and scientists said the telescope is already collecting “early release observations” that NASA, along with the European Space Agency and Canadian Space Agency, will unveil July 12. Those observations are taking place as engineers finish preparing the telescope for routine science observations, with 15 of its 17 observing modes now commissioned.JWST’s technical performance continues to exceed expectations. Lee Feinberg, JWST optical telescope element manager at NASA’s Goddard Space Flight Center, that the telescope had a requirement that its resolution be diffraction limited — that is, its sharpness limited only by the laws of physics — at wavelengths as short as 2 microns. He said the telescope was in fact diffraction limited down to 1.1 microns.
